$11 @ PR; Top 2 vs possible flush draw

[Marcotte]

I think I played this right, but want to make sure. twodimes puts the odds closer than I thought.

First orbit, blinds of 10-20. I had played 3 of the first 5 or 6 hands, winning the fist one to put me at about 1600 chips.

UTG I get A [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/spade.gif[/img] and raise to 80. Get about 4 callers so there is ~400 in the pot. Flop is A [img]/images/graemlins/club.gif[/img]K [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]. SB checks, BB bets 20, I make pot sized raise. Guy behind me min raises and everyone folds to me and I go all in (have him covered by 50 chips). He calls.

I put him on a flush draw, probably with the A [img]/images/graemlins/diamond.gif[/img].
If that's the case, is this the right line? Or is it better to call the flop and push the turn if it's not a diamond?
